产品特点及用途
氢氧化镁
分子式：mg（oh)2
分子量：58.32
英文名：magnesium hydroxide
物理性质：无色六方柱晶体，密度2.36,不溶于水
化学性质: 在380℃分解而成氧化镁。
是中强碱,溶于水的部分全部电离，产生mg2+（50%）、oh-（8%）（和[mgo2]2-（或写作[mg(oh)4]2-）和[mgo3]4-（或写作[mg(oh)6]4-）（42%）。
我们一般将溶于水电离为金属阳离子和羟基配合物及一部分氢氧根的氢氧化物称为中强碱。具有碱的通性。
物化性质白色晶体或粉末。水溶液呈碱性。2.36g/cm3。溶于稀酸和铵盐溶液，几乎不溶于水和醇。在水中的溶解度（18℃）为0.0009g/100g。易吸收空气中的二氧化碳。在碱性溶液中加热到200℃以上时变成六方晶体系结晶。在350℃分解而成氧化镁和水。高于500℃时失去水转变为氧化镁。沸水中碳酸镁可转变为溶解性更差的氢氧化镁。粒径1.5-2μm，目数10000,白度≥95。
用途氢氧化镁广泛用于pe，pp，pvc，abs，ps，hips，pa，pbt，不饱和聚酯，环氧树脂，橡胶，油漆的阻燃填充剂，化工，环保等工业领域；用于塑料、橡胶等高分子材料的优良阻燃剂和填充剂，在环保方面作为烟道气脱硫剂，可代替烧碱和石灰作为含酸废水的中和剂；用作油品添加剂，起到防腐和脱硫作用；用于电子行业、医药、砂糖的精制；用于保温材料以及制造其它镁盐产品。
普通氢氧化镁：普通氢氧化镁：应用于橡胶、塑料、油漆、涂料、化工等行业。
活性氢氧化镁：活性氢氧化镁：活性氢氧化镁阻燃剂，广泛应用于橡胶、化工、建材、塑料（聚丙烯、聚乙烯、聚氯乙烯、三元乙丙橡胶）及电子、不饱和聚酯和油漆、涂料等高分子材料中，特别是对矿用导风筒涂覆布、pvc整芯运输带、阻燃胶板、蓬布、pvc电线电缆料、矿用电缆护套、电缆附件的阻燃、消烟抗静电，可代替氢氧化铝，具有优良的阻燃效果。外观：白色晶体或粉末。

magnesium hydroxide
molecular formula: mg (oh) 2
molecular weight: 58.32
english name: magnesium hydroxide
physical properties: colorless hexagonal prism crystal, density 2.36, insoluble in water
chemical properties: at 380 ℃ decomposition and magnesium oxide.
is in strong alkali, all part of the ionization is dissolved in water, producing magnesium 2 + (50%), oh - (8%), and [mgo2] 2 - (or writing/mg (oh) 4 -) 2 and 4 - [mgo3] (or [mg (oh) 6] 4 - writing) (42%).
we generally will dissolve in water and electricity for the metal cation and hydroxy complexes and part of hydroxy alkali hydroxide is called. connectivity with alkali.
physical and chemical properties of white crystal or powder. aqueous solution is alkaline. 2.36 g/cm3. soluble in dilute acid and ammonium salt solution, almost insoluble in water and alcohol. in water solubility (18 ℃) is 0.0009 g / 100 g. easy to absorb carbon dioxide from the air. when heated to above 200 ℃ in the alkaline solution crystallization into six-party crystal system. decomposition and magnesium oxide and water at 350 ℃. higher than 500 ℃ when losing water into magnesium oxide. boiling water magnesium carbonate can be transformed into poorer solubility of magnesium hydroxide. particle size of 1.5 2 microns, item number 10000, p. 95
use magnesium hydroxide is widely used for pe, pp, pvc, abs, ps, hips, pa, pbt, unsaturated polyester, epoxy resin, rubber, paint flame retardant filler, chemical industry, environmental protection and other industrial fields; for good flame retardant polymer materials such as plastic, rubber and filler, in environmental protection as the flue gas desulfurization agent, but instead of caustic soda and lime as a neutralizer of wastewater containing acid; used as oil additives, have antiseptic and desulfurization effect; used in electronic industry, pharmaceutical, sugar refining; used in thermal insulation materials and other magnesium salt manufacturing products.
ordinary magnesium hydroxide: normal magnesium hydroxide: used in rubber, plastic, paint, coating, chemical industry, etc.
active magnesium hydroxide: active magnesium hydroxide, magnesium hydroxide flame retardant is active, is widely used in rubber, chemical industry, building materials, plastic (polypropylene, polyethylene, pvc, epdm) and electronic, unsaturated polyester, and the paint, coatings, such as polymer, especially to mine air duct, pvc coated cloth whole core conveyor belt, flame retardant plastic board, tarpaulin, pvc wire and cable, mining cable sheath, cable accessories, antistatic, flame retarding and smoke suppression of aluminum hydroxide can be substituted, it has excellent flame retardant effect. appearance: white crystal or powder.
storage: packing: the product packed in composite paper bag, inner with plastic film bag, bag of 25 kg net each. handling storage: light moving light, sealed preservation, do not be affected with damp be affected with damp.
